KNOCKDOWN AND PORTABLE FRAME AND I-IOIST.

To all whom it may concern:

Be it known that 1, Jnssrn A. SHOOK, a citizen of the United States,residing at Bronte, in the county of (Joke, State of Texas, haveinvented. a new and. a useful Knockdown andv Portable Frame and lzioist;and 1 do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. V This inventionrelates to .a hoisting apparatus for hoisting various commodities.

'One of the objects of the invention is to provide a hoist including animproved combined knock down and portable frame, whereby the entirehoisting apparatus may be arranged in acomparatively small compass foreasy and convenient transportation from one place to another.

A further object of the invention is to provide a top beam consisting ofa plurality of parallel strips or bars suitably spaced by spacingblocks, the spacing blocks at the ends of the beam being so arranged asto afford sockets for the reception of the supporting legs.

In practical fields, tion may necessitate alterations, within the scopeof what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in side elevation of the improvedhoisting apparatus constructed in accordance with the invention.

Fig. 2 is a plan view, showing the bars or strips of the beam suitablyspaced by spacing blocks.

Fig. 3 is a detail perspective View of one end of the beam, showing thesockets or openings for the reception of the extension of the supportinglegs.

Fig. 4c is a detail perspective view of one pair of supporting legsshowing the extensions thereof in position ready to enter the sockets oropenings of the beam.

Referring more especially to the drawings, 1 designates an elongatedbeam which comprises a plurality of parallel bars, two outer bars 2, andan intermediate bar 3, which are held spaced by the spacing blocks ormembers 4 and 5 at the ends of said beam, and by the central spacingblock 6, there being bolts 7 passing through said bars and the detailsof construc- Specific'ation of Letters Patent.

blocks, and provided with nuts 8 to hold and parts firmly and rigidlytogether.

The spacing blocks a and 5, respectively, are spa-cedfrom each other, inorder to form the openings or sockets 9. Thebeam 1 is supported by twopairs of supporting legs 10 and 11. The legs of each pair are arrangedto converge together upwardly, and are held so arranged by thetransverse beams or bars12, 13 and 14:, vwhich are disposedtransversely. Both pairs of legs are inclined toward each other, and theupper ends of said legs terminate in extensions 15, and where theextensions-mergeor extend from the legs, shoulders 16 transverse barsor'pieces 12 to 1 1 so brace or reinforce the legs as to prevent themfrom moving longitudinally. To further prevent such movement,intersecting bars or strips 17 are arranged to connect the legs. Thelegs of each pair are so disposed as to provide spaces 18 between theextensions 15 of the legs, whereby said extensions, when receivedin thesockets or openings 9, engage on both sides of the intermediate bar orstrip of the beam, so that the beam will rest upon the shoulders 16 andthe transverse bars 14, thereby rigidly supporting the beam 1. Arrangedin the spaces 19 and 20 between the bars 2 and 3, and mounted upon thepin 21 are pulleys 22 and 23. Arranged in the space 20 and mounted uponthe pin 24:, is a pulley 25. One end of a cable 26 is attached to an eye27 of a bolt 28, which is carried by one of the bars 2 of said beam 1. Awindlass 29 comprising a crank shaft 30 (which is mounted in bearings ofthe legs 11) and a winding drum 31 (which is carried on the shaft) isprovided, and to the drum of which one end of a cable is attached. Thecable 32 is wound partly on the drum and its other end has an eye 33.The cable 26 extends downwardly from the eye 27 and passes over thepulley 34 of the block 35 (which is provided with a coinmodity engaginghook 36) and upwardly over the pulley 22, then downwardly and under theother pulley 37 of said block. The cable 26 after passing under thepulley 37 extends upwardly and over the pulley 23, then over the pulley25, whereby its hook 38 may engage the eye 33 of the cable 32. By thisconstruction, of hoisting apparatus, various commodities may be raisedby attaching them to the hook 336 and subsequ'ently imparting revolublemovement to are formed. The
